Regional electricity planning in the Toronto region is divided into two sub-regions – Central Toronto and Northern Toronto.
Regional planning activities in the Toronto region
Central Toronto sub-region
An Integrated Regional Resource Plan (IRRP) was released for the Central Toronto sub-region in April 2015.
An addendum to the Central Toronto sub-region was completed in February 2017. See the details.
Northern Toronto sub-region
A Needs Assessment for the Northern Toronto sub-region, the first step in the regional planning process, was completed in June, 2014. The study team determined that the needs identified for this sub-region can be addressed directly by the transmitter and local distribution companies, and that further regional coordination is not required. See the Needs Assessment report on Hydro One's website.
Hydro One completed a Regional Infrastructure Plan for the Toronto Region in June 2016, available on Hydro One’s website.
Toronto region Working Group
A Working Group, consisting of the local distribution company in the region, Toronto Hydro-Electric System Limited, the local transmitter (Hydro One) and the IESO, are using the regional planning process to identify and meet local electricity needs.
